I mostly don’t like flip flops…they either look TOO casual, or they hurt your feet. But after much digging online I found TKEES. They are supposed to “disappear” on your foot, and they even have a bunch of different flesh toned flops so you can pick a pair that will match your skin tone!
Not only do they have the ones above and the nude sandals, they also have a ton of neons, metallics, etc. At $50 they aren’t free but all reviews say that they are comfortable, beautiful and long lasting. I wish I had all the pairs right now.
